标题：Original quantitative research – Age at first alcohol use predicts current alcohol use, binge drinking and mixing of alcohol with energy drinks among Ontario Grade 12 students in the COMPASS study
摘要：Introduction: The recent rise in mild traumatic brain injuries (mTBI) in the pediatric
population has been documented by many studies in Canada and the United States. The
objective of our study was to compare mTBI rates from the Canadian Hospital Injury
Reporting and Prevention Program (CHIRPP) in Montréal with population-based rates
(Quebec mTBI rates).
Methods: We calculated CHIRPP’s mTBI rates via two methods: (1) using all CHIRPP
injuries as the denominator; and (2) using the number of children aged 0 to 17 years
living within 5 km of either of two CHIRPP centres in Montréal as the denominator. We
plotted CHIRPP’s mTBI rates against the provincial rates and compared them according
to sex and age.
Results: Whether using all CHIRPP injuries or the number of children aged 0 to 17 years
living within 5 km of either CHIRPP centre in Montreal as the denominator, CHIRPP
paralleled the fluctuations seen in Quebec’s rates between 2003 and 2016. When stratifying
by sex and age, CHIRPP was better at estimating the population-based rates for
the youngest (0 to 4 years) and the oldest (13 to 17 years) age groups.
Conclusion: CHIRPP in Montréal proved a valid tool for estimating the variations in
rates of mTBI in the population. This suggests that CHIRPP could also be used to estimate
population-based rates of other types of injuries.
